Synopsis

The remote Debian host is missing a security-related update.

Description

The regular expression engine of Ruby, a scripting language, contains a memory leak which can be triggered remotely under certain circumstances, leading to a denial of service condition (CVE-2008-3443 ).

In addition, this security update addresses a regression in the REXML XML parser of the ruby1.8 package; the regression was introduced in DSA-1651-1.

Upgrade the Ruby packages.
